HAMWORTHY INTERNATIONAL LTD
Company number 00713227 · Monitor this company
Executive summary
Hamworthy International Ltd has delivered a striking financial turnaround in FY2025, swinging from a £4.4m operating loss to a £5.7m profit and restoring positive equity—albeit to a thin £618k on a £38.5m revenue base that signals ongoing balance sheet fragility. Operating within the regulatory-driven marine equipment sector, the company benefits from strong IMO compliance tailwinds and Wärtsilä group backing, but faces competitive headwinds from lower-priced Far Eastern manufacturers and a declining revenue trajectory that raises questions about market share retention. The 1% R&D-to-revenue ratio appears light for a business positioning on "engineering excellence," and the five name changes in 25 years suggest strategic restlessness within the group structure.
